Herwith I add a .xsession-errors without the issue being triggered. The most striking thing are the following two lines missing (which are present when the issue occurs).
** (gnome-settings-daemon:1423): WARNING **: You can only run one xsettings manager at a time; exiting ** (gnome-settings-daemon:1423): WARNING **: Unable to start xsettings manager: Could not initialize xsettings manager.
